INTERKAL-CO MBUSTION ENGINE.

Specification oi Letters Patent. Patented May 25, 1909.

, Application filed November s, 1907. Serial no. 401,305.

Be it known that l- THOMAS DANnaL KELLY, a subjectof theiiiiigfof GreatBrit ain, residing at 20 Chi? avenue, Westcliti-on- Sea, Essex, England,engineer, have invented certainnew and useful Improve ments .inInternal-Combustion Engines, of

which the following is a specification..

The present mventionrelates to improvementsin internal combustionengines oi-the two cycle type and wherein a set-of three cylindcrs or amultiple thereof is employed, the cranks of the engine serving totime'the op- Qerations of the pistons so that each cylinder will operateone-third of a revolution in ad- .vance of the'next cylinder so that theengine pistons and pumpsflwill so operate that at each revolution of thecrank shaft, power is imparted thereto from any one piston duringone-third of therevolution ofthe shaft, the discharged and new exhaustgases are charges are bemg admitted to the respective cylinder duringanother third of the reyolw.

' tion of the shaft, and compression is taking place during anotherthird of the revolution. of the crankshaft.

Another object of the invention is to provide an improved engine of thischaracter from the main to a muffler while the auxiliary port maydischarge into the atmosphere, and wh-ileithe'se' auxiliary ports of thecylinder are open tothe atmosphere,

explosive ports thereof are I-F-ig. 1.

Wherein the main exhaust port of each cylinder opens preliminarily tothe opening of an auxiliary exhaust port, the gases exhaustel exhaustport being conducted the incoming charges of the mixture cause the deadgases to be discharged therethrough, back pressure be ing therebyeliminated.

A further object fthe gases are discharged of the engineare'cooled; hThe annexed "drawings illustrate-how '1- carry my invention into effect:I Figure 1. is a sectional: elevation'o ':pistoris,' connecting pipes,end elevation of -ing-their positions When'the pistons" are as -at Fig.3.. is a diagram of the working pistons stroke. Fig. d-i'sa-diagram' ofthe pump stroke, A-to B'indicating'suct'ion, B to 3 compression, and-Cinvention is to provide means for introducing mixedfairf-and water intothe .cylinders'while the exhaust: open whereby the exhaust and theworking-parts? I pump i -three t A'P mip e thrives elevation (enlarged)of the air and Water scavenging valves and the box.

The pistons 1, 2 and 3 with their pumps 4,

in a Wellknown manner, each piston being connected by. a rpd to acrank.'1(),'1l and 12,

sitioned at 120 degrees'with each other or 1n other words at equaldistances around, the circumferential travel of the crank shaft 13. Inthis position, the piston 1 is situated at the top of the stroke, piston2 two thirdsof the down stroke and piston 3 one third of the upstroke.

At the head of each cylinder or at other suitable part is situatedaninlet valve 14, 15, 16, these opening from the cylinder each into abox 17, 18 or 19, each of-which boxes is provided With an air inletvalve 20, 21, 22, and also awatervalve controlled by needles 27, 28, and29, the Water pipe 30, 31, 32 leading to the seatings of. the valves 20,.21, 22..

Each box 17,18,19 has a pipe 33, 34, 35, the pipe 33 leading-to thecylinder 36 of the pump piston 5, the pipe 34 leading to the cylinder-37of the ump piston 6, and the pipe 35 leading to t e cylinder 380i. thepump piston 4. y 39, 40 and 41 are the combustion mixture inlet Valves;

A set of pipes 42, 43 and 44 extendi'rom the respective engine cylindersand lead to oneor-more muiiiers of any suitable construction. v v

45, 46 ande17 are auxiliary exhaust ports leading to the atmosphere.

' In the position shown, received theexplosion, and is on the downwardstroke. Piston 2 has been moved down by the expansive force of-theexplosion in its cylinder, and is just reaching the main exhaust' 43.Piston 3 is one third of its travel on the up stroke, and is commencingtoacoinpress the combustible mixture forced. into the cylinder 9 by the]previous upstroke of the 4. On theld'ownstroke ol' the pump 5 [air hasbeen drawn into the. pipe 33 and cylinder'36, through the valve. 20,and'at the same time Water haslbeen drawn in with the air drawn intothe-cylinderac by' the pump 5 throughthe valve .41),

being closer thanthe air and .water supply is drawn in next to thepiston 5, so'th at on the ejection, the .Water and air into workingcylinder. Fig. 5. is a sectional of the crank. shaft 13. .These cranksare pothe piston 1 has just [from the; supply pipe 30, also .a charge ofgas drawn into the 5 and 6 are arranged in cylinders 7, 8 and 9,

charge. ofcombustible mixturev tln'ough thc'vnlve .41

and-also the air and water through the valve '21'andpipe 31respectively, but in the position shown the pump is just about to ejectthe'water'and air through the pipe 3-} into lthe cylinder 8, which it.does' immediately after the main exhaust 43 is open, so that thepressure is released in the. cylinder 8 to allow of the pressure in thecylinder 37 overcoming the valve v15. The piston 11 is now on its downstroke; andsosoon as it reaches the -m'ain-'exhaust 42, the expansiveproducts of combustion exhaust themselves through the gases pass away,-I air and water from the cylinder 36 and its same of the remaininggases, followed by the 01 gas and air and" also water exhaust 42 andpass away. As the exploded the scavenging charge of pipe --33 pass intothe. cylinder to clear combustible charge from the cylinder 36. Just asthe piston 1 passes the exhaust 42,

the auxiliary exhaust 45 is opened, so the remammg gases may be forcedout without, be-

ing checked by the exhaust gases in the silencer, thus creating a cleancylinder each time. -During the downward movement of this piston, thepump has-drawn in a charge viouslymentioned with regard to pump 5. Thepiston 1 has now'reachedthe end of the downward portion of thestroke,and com- Inenced the upward portion of the stroke to I cylinder throughthe compress the combustible charge in its cylin der 7, th

0 pump 4 forcing the charge in its 38 and the airand gas in the pipe 35,pipe 35 into the cylinder 9, the act-ion of the different pistons andpumps being'in sequence.
